. PIGl'ZING SHUTTLE-ACTUATI'NG MECHANISM FOR LOQMS.

Application filed September 1a, 1913.

To all whom it may concern:

Be it :nown .that I, GEoao-n WILSON Elrracnnnrort, a subject of the King of Great Britain, and resident of Eraithwaite, Keighiey, in the county of York, England, have invented a certain new and useful Improvement rippertaining to Picking or Shuttle- Eiictuating tiechanism for Looms, of which the following description, having reference to the accompanying sheets of drawings, is a specification. j

It relates to the type or class of picking or shuttle actuating mechanism for looms wherein it is necessary that the actions'of said mechanism should from time to time be entirely suspended or arrested, such for example, as in looms having series of shutthe boxes and other devices that necessitate a reversal in the direction of motion of certain of their mechanisms when performwhich time the clutch on the opposite side of the loom is out of gear as is well understood) the movement of a handle by the weaver or attendant (or the movement of a lever by mechanism such as is used for automatically finding the last or broken pick or shot of weft) will throw said clutch out of gear without disturbing the'other clutch and that ina iianner which is etlicient for this purpose, as well as for operatingthe clutch mechanism to carry out the usual changes in the functions of the picking cams during the ordinary weaving operations of the loom. V i

In the accompanying sheets of-drawings whichare illustrative of my invention: Figure 1 is a front elevation'showing the low shaft or that shaft of a loom upon which the icking camsor clutches operating the picking bowls are mounted, my said apparatus being shown. arranged in connection therewith. Fig. 2 is an end elevation of the parts shown to of Fig.1, and as Specification of Letters Patent.

seen in the direction indicated by the arrow Fig. 8 is a similar view to Fig. 2 but i'lustrates my improved parts alone, the aine being drawn to an enlarged scale. ig. at shows my improved parts as deached from the loom and as seen from the "rent of said loom; Fig. 5 is a plan showing the parts illustrated by Fig. l. Figs. 6 and 7 are similar views to Fig. but illustrate certain of the parts in the positions they assume under the conditions hereinafter described.

A is the low shaft or picking s-aft of a loom, and show the cross 1' of said loom which aiford surmort for said shaft A. Upon the shaft A keyed or fixed the clutches 2, 2 into w 'ch slidethe other parts ofthe clutches 3, .3, said clutches 3 and 3 being arranged to be moved longitudinally upon the shaft A by means of the foil levers l, l so that when said clutches 3 anc 3 are in certain positions they will carry their bowls or cam actuators 5 and 5 to actuate their respective picking cams 6, 6", upon the picking shafts 7 and 7 in manner well understood. The levers 4: and P are usually connected together by a connecting rod extending between them in order that a lever 8 (which is actuated by a rod 8 to be moved according to the indications of the pattern surface of the loom) may be made to actuate the lever l and therefore also the lever 4. According to my invention I make the lever 8 separate from the lever -l and mount it loosely upon the stud d upon which is also mounted loosely said lever l, while the connecting rod instead of reaching to the lever (which lever 43 is pivoted upon its stud l) is connected to a lever 9 constructed and arranged in accordance *ith my invention. The rod i which is pivotally'connected to the lever is connected to a lever 10 and said levers 9 and 10 are levers constructed and arranged in accordance with my invention. ihe levers 9 and 10 are mounted loosely upon their stud 11 which is carried by being fixed to l ails the bracket 12, which is fixed to the cross rail B.- Mounted loosely also upon the pivotal stud 11 is the lever 13, which by the rod 13 is connected to the lever 8 thus as said lever 8 is operated through its rod 8 by the pattern surface mechanism so also is the lever 13. The levers 9 and 10 have 2 1, and. 10 re pecti ely hi h Project beyond their pivotal stud 11, so that they may be connected together by a retracting spring 14, which draws them toward each other or tends to draw them toward each other to keep the lower arms 9 and 10in normal positions. Extending beyond the same center 11 of the levers 9 and 10 are projections 3 and 10 respectively and these are of such a shape that when the levers are free to be actuated by their spring 14, said arms 9" and 10 are brought against a projection 13 which extends laterally from the lever 13, thus provided the spring let is not distended, whenever the lever 13 is oscil lated on one side or the other of its vertical center, so will the lower arms of the levers 9 and 10 be oscillated from side to side as will be understood.

The lever arms 9 and 10 have hubs formed upon them so that projecting pins 9 and 10 may be fixed within said-hubs and made to project laterally therefrom, as shown by Fig. 5. These pins 9 and 10 are sufficiently long tov extend over projections 12 and 12 which extend laterally from the bracket 12, thus the downward movement of the pins 9 and 10 is arrested by said projections 12 and 12 ashereinafter explained. Taking over, and with its extending ends resting upon said pins 9 actuated whenever the picking motion has to be thrown out of gear. The weight of the lever-15' its rod 15 and the lever 15 is counteracted by the spring 15. 7

The actions of these parts are as follows :During the ordinary weavingoperations of the loom the lever 15 lightly presses or rests upon the pins 9 and 10 and there fore the spring 1 1 is enabled by being strong enough to press said levers with their'projecting arms 9 and 10 against the laterally projecting arm 13 of the lever 13. In this manner as the lever 13 is oscillated by means of the'pattern surface mechanism through the lever 8 and rod 8 above referred to, said levers 9 and 10 are oscillated. In one position,'as in the position shown by Figs. 1, 6 and 7, the lever 9 has withdrawn the lever 4 so that the picking clutch 3 brings away the picking bowl 5 out of the path of motion of the cam 6, while at the same time the lever 10 being in the opposite position to the lever 9 (as is shown in Figs. 1 and 6) the clutch 3 and consequently the bowl 5 are brought into the path of the cam 6. When the lever 13 is moved to the. opposite side of its vertical center (as shown by Fig.

7) the positions of the bowls 5 and 5 are reversed, that is tosay, the bowl 5 is then brought into position for actuating the cam 6, while the bowl 5 is'brought out of the position for actuatingthe cam 6.

When for any reason, such as during the process of lagging back or otherwise, it is desired that both of the bowls 5 and 5 should be out of positionfor actuating their cams 6 and 6, then the shaft. 16 is actuated by the lever 17 through the rod 17 (which as is hereinbefore stated, is moved either by the weaver with proper or appropriate handle devices, or which is connected to cam or other mechanism automatically actuated during the time oflagging back, and which mechanism is well known as automatic pick finding mechanism) so that by the lever 15 secured to said shaft 16, the rod 15*.is caused to descendand pull down the lever 15. The descent of the lever 15 is limited by the stop pieces 12 and 12 arresting the pins 9 and 10 as above described, so that provided the lever 13 is in the position shown by Figs. 1 and 6 (in which case the pick finding bowl 5 is' already out of the path of motion of the cam 6) on the descent of said lever 15 which forces down the pin 10 and brings with it the arm 10 against .the retracting actions of the spring 14. the

arm 10 is moved to cause the rod 1" to withdraw the bowl 5 from the path in which its cam6 lies. On the other hand, provided the lever 13' is in the position to the opposite side of its center as is shown by Fig. 7, in which position it has caused the lever 10 to withdraw the bowl 5 from being in the path of its cam 6, on said lever 15 being caused to descend its opposite end will bring down the pin 9 to rest upon the stop piece 19. as shown by Fig. 7, hence. the lever 9 is at this time moved into the position also shown by Fig. 7, to withdraw the bowl 5 from the path in which it moves to actuate the cam 6. The respective positions from whichthe levers 9 and 10 are moved by the lever '15 are shown in broken lines in said Figs. 6 and 7. v

By the employment of lever devices according to my said invention and as hereinbefore described, the disengaging of the picking mechanism is readily effected without disturbing any of the pattern surfaces or other mechanism of the loom, and when the reengagement of the picking mechanism is effected all the parts of the loom are thus enabled to retain their proper respective positions to continue their effective opera tions as will be understood.
